A novel porous magnet consisting of cationic two-dimensional (2-D) layers extended by Fe-CN-Ni linkages and pseudo-pillar dianions was synthesized. The size-selective guest adsorption behaviour of water and methanol molecules originates from the narrow bottle-neck-type pores in the flexible pseudo-pillared-layer structure, which results in the switching of the magnetic phases from antiferromagnetic to ferromagnetic, involving significant changes in the interlayer distance.
合成了一种新型多孔磁体，它由通过铁 - 氰基 - 镍键延伸的阳离子二维（2 - D）层和假柱双阴离子组成。水和甲醇分子的尺寸选择性客体吸附行为源于柔性假柱层结构中的窄瓶颈型孔，这导致磁相从反铁磁转变为铁磁，涉及层间距离的显著变化。
